Fedora PPC things...

Thanks, that's a nice list. I can't think of anything to add right now, 
but it feels like a good occasion for commenting on my experience with 
some of the points (Powerbook G4 Ti 867MHz, 768 MB RAM, Radeon Mobility 
9000).

Xautoconfig generated a working fbdev configuration for me. I then 
edited it to use the radeon driver with UseFBDev, which at least gave 
me 2D acceleration. Removing UseFBDev or trying 24 instead of 16 bit 
didn't work however (I don't remember the exact symptoms for each case 
- sometimes I got a screen full of weird flowing colors, sometimes X 
just hung). I had 24 bit video and 3D acceleration working on this 
machine in FC2, so I hope some more tinkering will bring it back... 
Could this be related to the kernel? I'm using dwmw2's 2.6.10-1.744.

In my limited experiments, snd_powermac worked just as well as 
dmasound_pmac. I didn't try system-config-soundcard.

I've always used pbbuttonsd in the past (and liked it). Since it seems 
to be somewhat deprecated here 
(https://bugzilla.redhat.com/beta/show_bug.cgi?id=120809), I tried 
going with the other solution this time. Pmud (after I finally found it 
in dwmw2's FC2 packages) made sleep work, but I can't figure out how to 
make the brightness, volume, and eject keys work. I didn't find any 
package or program named "acme", none of Gnome's control panels seems 
to offer anything relevant (maybe I just didn't look hard enough?), and 
some web research turned up no results either. By the way, I don't 
quite like the idea of having Gnome handle this - these things should 
work everywhere, not just in Gnome.
